Serial No. 663,045.

To all whom t may concern Be it known that I, JULIUS Gr. MAT'rsoN, acitizen of the United States, residing at Plumb, in the county ofBecker, State of Minnesota, have` invented certain new and usefulImprovements in Loaders; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to loaders, more particularly to that class ofloaders designed for permanent mounting in the barn or the like.

An object of the present invention is to provide a metal trough thesides of which are equipped with alining grooves which form guide waysfor the gudgeons of the scoop, a portion of the trough having a cementfloor so that corrosion of the device will be reduced to a minimum.

With the above object in viewithe invention consists in certain novel,detailsof construction and combination of parts hereinafter fullydescribed and claimed, it being understood that various modificationsmay be made in the minor details of construction within the scope of theappended claims.

In the accompanying drawings forming part of this speciicationz-Figure 1is a plan view of my improved loader. Fig. 2 is a longitudinal sectionalview through the loader. Fig. 3 is a cross sectional view taken on theline 3-3 Fig. 2. Fig. 4 is a longitudinal sectional view through` thewinding drum. Fig. 5 is a cross sectional view taken on the line 5-5Fig. 2.

Referring now to the drawings in which like characters of referencedesignate similar parts, 10 designates the iooring of a barn or thelike, and for the reception of the loader a pit 12 is formed in thefloor, the pit being oblong in contour. The loader comprises parallelmetal side plates 13 which are held in position by substantially U-shaped straps 14, the legs ofwhich `extend upwardly along the plates andare riveted or otherwise secured thereto. The upper ends of the legs arebent outwardly as shown at 15 and are fixed to the flooring in anypreerred manner. A cement bottom 16 connects the lower edges of the sideplates and coperates with the latter in forming a trough for thereception of a hereinafter described scoop. The side plates are providedin their inner faces and near their upper longitudinal edges withlongitudinal grooves 17 `which are preferably square in outline and formguide ways for the gudgeons of the scoop. The side Vplates are bentabruptly upwardly through the side of the barn as shown at 18, and asheet metal bottom 19 connects the lower -edges of the plates, thebottom having a marginal iange which extends upwardly along the outerfaces of the sides and is bolted or otherwise secured thereto. The upperlongitudinal edge portions of the inclined sides areybent outwardly asshown at 20, and serve to direct material` falling from the scoop backinto the trough. The upper end of the metal bottom 19 terminates shortof the extreme end edges of the sides as shown at 21 and forms means fortilting the scoop as will presently be described. The inclined lsides 18and metal bottom 19 are securedtogether by substantially U-shaped straps22 which are riveted or otherwise secured to the parts as` shown in Fig.5. l Y

Thex scoop comprises a bottom 23 from the rear ends of which rises avertical rear wall 24 and from the side edges of which rise verticalsidel walls 25, the latter bearing against the sides of the trough.Arranged at diametrically opposite points in thescoop sides are openings26which receive the cylindrical necks 27V of approximately squaregudgeons 28 which project into the guide ways 17-01 the trough sides.The inner ends of the necks are headed up as shown at 29 to retain thegudgeons in position. By virtue of the squared gudgeons engaging in theguide ways, the even advance of the scoop in the guide ways isassured,while at the same time by virtue of the cylindrical necks of thegudgeons, the scoop may rock upon the gudgeons when it arrives 1at thedischarge end of the trough as shown in dotted lines in Fig. 2 andpermit of the scoop emptying its contents into the wagon or otherconveyance designed for its reception. A substant-ially U-shaped bailstrap 30 is riveted or otherwise secured to the inner sides of thescoop, the bridge 3l of the strap being disposed on the bottom face ofthe scoop bottom as shown in Fig. 2 and forming a shoe for the scoopwhich will minimize friction of the scoop against the bottom of thetrough during its movement therein, y

The extremities of the strap legs project beyond the upper edges of thescoop sides and are provided with openings for the branched extremity ofa bail 32, this bail being connected to a hauling cable which extendslongitudinally through the trough and is connected at its outer end to anovel .horse power which will be presently described. The hauling cableserves to move the loaded scoop to the discharge end of the trough, andfor returning the empty scoop to its initial position, an eye 33 isfixed to ythe trough and will be used as hereinafter described.

The horse power for actuating the scoop consists of a turning stile 35the lower end of which is pivoted in a block 36 in any Vpreferredmanner, and the turn stile is equipped with a draft sweep 37 to which anattaching iron 38 of any preferred type is secured. The upper end of theturning stile is journaled in an eye 39 arranged centrally on the bowed.rod 40 to the opposite ends of which are secured horizontally disposedbrace rods 4l which are terminally secured to the side plates 18 nearthe discharge end of the trough. Upwardly inclined brace rods 42 aresecured to the "horizontal brace rods and to the side plates andcooperate with the horizontally disposed brace rods in rigidlysupporting the rod 40 in stationary position. Looselv mounted on theturning stile is a drum 43 lhaving. a circular flange 44 at one end ingcable 46 is terminally secured at one end to the drum, and is attachedat its opposite end through the instrumentality of a hook and eyeconnection 47 to the rod 40 the loop thus formed in the cable beingtrained through a pulley block 48 secured to the bail 32. Upon rotarymovement of the turn stile, the cable is wound upon the drum and thescoop advvanced to the discharge end of the trough. `To effect thereturn of the scoop, the pulley ,block is attached to the eye 33 abovementioned while the hook 47 is attached to the ways, each of said sidesbeing directed abruptly upwardly at one end, a plurality ofsubstantially U-shaped straps having their bridges engaged transverselyacross said sides and having their legs extended upwardly along thesides and rigidly lixed thereto, a bottom connecting the sides remotefrom their upwardly directed ends and bearing upon the bridges of saidstraps, said bottom being formed of hardened plas- S5 tic material, anda bottom connecting said sides at their upwardly directed ends, the lastnamed bottom bearing upon and being supported by the bridges of thestraps connecting said upwardly directed ends, said second named bottomfurther forming a continuation of said irst named bottom, and a scoopmountedy for movement in said trough and having gudgeons bearing withinsaid guide ways.

.2. A loader including a trough having side walls provided withlongitudinal grooves in their inner faces forming guide ways, each ofsaid sides having an outer end portion inclined upwardly, a plurality of100 substantially U-shaped straps having their bridges projecting acrosssaid sides and having their legs extended upwardly along said sides andrigidly secured thereto, a hardened plastic material bottom bearing uponthe bridges of said straps remote from said inclined ends, a secondbottom bearing upon the bridges of the straps carried by said inclinedends and forming a continuation of the firstnamed bottom, said secondnamed bottom terminating short of the extreme outer edges of saidinclined ends, and a scoop mounted for sliding movement in said troughand having gudgeons bearing within said guide ways, said scoop beingadapted to rock to unloading position upon the ext-reme free edge ofsaid second named bottom as a fulcrum.

3. A loader including a trough having a substantially horizontal endportion, and having its opposite end portion inclined upwardly, thesides of said trough being provided in their inner faces withlongitudinal grooves forming guide ways, a scoop mounted for slidingmovement within said trough and having gudgeons bearing within saidguide ways, a substantially U-shaped bail cable operating to advance andto retract strap carried by said scoop having its legs said scoop insaid trough. projecting upwardly along the scoop sides, In testimonywhereof, I atix my signaztnd having its bridge portion projecting ture,in presence of two witnesses.
